RTV 664 AB
Master Molder RTV600 series is comprised of RTV662, RTV664, and RTV668. Each is a two part, addition (platinum) curing mold making product offering high durometer for applications requiring greater dimensional stability. 模具用胶RTV600系列包括RTV662,RTV664和RTV668。均为双组份构成,应用于对硬度和稳定性都有极高要求的模具生产。 RTV662 offers the highest durometer (68 Shore A) in the series, as well as the longest worklife. It is ideally suited for embossing, release rolls, and large molds. RTV664 is a high durometer (62 Shore A), long work life product. It offers excellent chemical and abrasion resistance and was designed for high production on manufacturing lines. RTV664是一种硬度高(62 Shore A),寿命长的产品,具有极好的抗化学反应和抗磨损能力,适用于生产量大的生产线 RTV668 is a high durometer (62 Shore A) product formulated for sulfur resistance. It is ideal for casting with masters made of pine, oak, and elm. |
